2. Arterial diseases treatment: The team can perform traditional open surgeries, such as endarterectomy, bypass/vascular reconstruction, artificial vascular replacement, carotid body tumor resection, and arteriovenous fistula surgery. It can also carry out minimally invasive treatments through endovascular intervention, such as thoracic endovascular aortic aneurysm repair/endovascular aortic aneurysm repair (TEVAE/EVAR), balloon angioplasty, and vascular stenting.

3. Venous diseases treatment: The team can perform minimally invasive treatments for great saphenous vein varicosity, hemangioma, and deep vein thrombosis and pulmonary embolism.

4. Hemorrhagic diseases treatment: The team can provide treatment for gastrointestinal hemorrhage, postpartum hemorrhage, post-percutaneous nephrolithotomy hemorrhage, hemorrhage in orthopedic surgery, tumor hemorrhage, and traumatic hemorrhage, etc.

5. Benign and malignant tumors treatment: The team can treat primary liver cancer, liver metastases, lung cancer, mediastinal tumors, etc., with interventional embolization therapy, percutaneous radiofrequency ablation, etc.

III. Thyroid and Breast Surgery:

1. Thyroid diseases treatment: The team provides diagnosis, surgical procedures, and drug treatments for a range of benign and malignant thyroid diseases, such as thyroid cancer, thyroid adenoma, nodular goiter, and hyperthyroidism. Surgical options include subtotal/total thyroidectomy, total thyroidectomy with central or lateral neck lymph node dissection, exploration of the recurrent laryngeal nerve, resection of parathyroid adenomas, and fine needle aspiration biopsy of thyroid nodules, etc., with a focus on endoscopic thyroid surgery and various complex and difficult thyroid surgeries, including those for goiter and substernal goiter.

2. Breast diseases treatment: The team specializes in diagnosis and treatment of a wide range of benign and malignant breast diseases, including breast cancer, breast hyperplasia, various types of mastitis, breast fibroadenomas, and intraductal papillomas. The services include minimally invasive rotational biopsy of breast nodules, radical breast-conserving surgery, modified radical mastectomy, sentinel lymph node biopsy, breast reconstruction using implants or autologous tissue, and one-stop comprehensive treatments such as chemotherapy, endocrine therapy, molecular targeted therapy, and immunotherapy.
